This is a very cool talk that highlights what can happen when science, medicine and art come together.  Mullins turns the idea of disability on its head and has redefined her missing legs around the needs of her life rather than the other way around.

From TED.com:

Athlete, actor and activist Aimee Mullins talks about her prosthetic legs — she’s got a dozen amazing pairs — and the superpowers they grant her: speed, beauty, an extra 6 inches of height … Quite simply, she redefines what the body can be.

A record-breaker at the Paralympic Games in 1996, Aimee Mullins has built a career as a model, actor and activist for women, sports and the next generation of prosthetics.
